To aZZ whom it may concern:

Be it known that 1, RILEY COLE, a citizen of the United States,residing'at Hudson, in the county of Lenawee, State of Michigan, haveinvented certain new and useful Improvementsin Grain-Drills; and Idodeclare the following to be a full, clear, and exact description of theinvention, such as will enable others skilled in the art to which itappertains to make and use the same, reference being had to theaccompanying drawings, and to the figures of reference marked thereon,which form a part of this specification.

This invention relates to grain-drills; and it consists in theconstruction and arrangement of parts hereinafter fully set forth,andpoint ed out particularly in the claims.

The object of the invention is to provide a grain-drill shoe. whereinthe arrangement is such as to regulate the depth at which the seed maybe planted, to deposit the seed in two parallel rows, and to provide forproperly covering the seed as the runner of the shoe passes through theground.

The above object is attained by the structure illustrated in theaccompanying drawings, in which Figure 1 is a side elevation of agrain-drill shoe embodying my invention. Fig. 2 is a plan view thereof.Fig. 3 is an inverted plan. Fig. 4 is an enlarged vertical section as online 4 4 of Fig. 1. Fig. '5 is a vertical section as on line 5 5 ofFig. 1. Fig. 6 is an enlarged rear elevation.

Referring to the characters of reference, 1 designates the shoe, to theupper portion of which the boot 2 is connected. The runner orfurr0w-opener3 of the shoe is inclined and narrow'at its forward end,while the rear of the runner flares outwardly in opposite directions,asat t,forn1ing outwardly-curved moldboards which undercut the soil andwhich are of such shape as to cause the soil to fall over the rear endthereof, so as to fillthe furrow made by the travelof the runner throughthe ground.

Extending downwardly through the boot and the rear portion of the shoeis the grainchannel 5, through which the grain passes from the hopper.(Not shown.) This grainchannel at its lower end is divided into curvedbranches 6-, which diverge from the main channel and open through thebottom of the shoe under the flaring sides of the runner.

By this arrangement the grain is equally divided and is deposited inparallel rows in the furrow, the point of discharge of the grain beingunder the curved flaring sides of the runner, so that the earth whichfalls from said curved sides over the rear of the runner perfectlycovers'the grain deposited in the furrow. By dividing the seed andplanting it in parallel rows the probability of a thrifty growth ismaterially increased.

The shoe proper is pivoted between the sides of a bifurcated gage-frame'7, which is fixed in any suitable manner to the draw-bar. (Not shown.)adapted to move or swing vertically within said frame comprises a pin 8,which passes through the sides of the frame and through the forward endof the runner 3 of the shoe.

Secured to the top of the runner is a metal strap 9, having apertures 10therethrough, through which a pin 11 is adapted to pass, the ends ofwhich are supported in the vertical ears 12 upon each side of the frame7.

.The bottom of the frame 7 is flat, as shown at 13, and affords a firmbearing upon the ground, serving as a gage to regulate the depth atwhich the tooth or runner of the shoe may enter the soil. By means ofthe ap ertures 10 in the strap 9 the shoe may be adjusted within theframe to regulate the depth at which the grain may be planted, accordingto the character and conditions of the ground.

The forward end of the gage-frame 7 is turned upwardly, as at 14, togive it the sh ape of a runner, so that it may the more readily passover the surface of the ground. I

The rear ends of the sides of the bifurcated gage-frame are connected bya cross-bar 15, whereby they are strengthened and prevented fromspringing. Upon the rear of the shoe is a removable plate 16', whichaffords access to the branches of the grain-channel for the purpose ofcleaning them should they become clogged.

- For the purpose of varying the weight upo the shoe according to theconditions of the ground weighted rings 17 may be employed,

'the sections of which are detachably united at their ends to enablethem to slip onto the boot 2, whereon they are supported by the Thepivot upon which the shoe is projecting shoulders 1 8. To afford meansfor raising the shoe, there is provided at the rear thereof an eye 19,into which a chain may be hooked, as will be understood.

Having thus fully set forth my invention, what I claim as new, anddesire to secure by Letters Patent, is-

1. In a grain-drill, the combination of the shoe, having a runneradapted to enter the soil provided with a flaring rear end and flatbottom, said shoe having a grain-channel passing therethrough, whichchannel at its lower end is divided into independent later ally curvedbranches whose ends open through the bottom of the runner adjacent theouter edges of said flaring sides.

- 2. In a grain-drill, the combination of the integral rigid gage-frame,the shoe pivoted at its forward end between the sides of said frame,means for aifording a vertical adj ustment of said shoe upon its pivot,said shoe being provided with a flaring runner adapted to enter the soiland having a grain-channel passing therethrough and discharging belowthe surface of the soil.

3. In a grain-drill, the combination of the fixed gage-frame havingbearing-faces at the sides, a grain-shoe pivoted between the sides ofsaid frame at its forward end, a strap attached to said shoe, ears uponsaid frame in alinement with said strap, and a pin adapted to passthrough the strap and ears to hold the shoe in position.

4. In a grain-drill, a shoe having means for regulating the depth atwhich it may enter the ground, said shoe having a runner provided with athin forward portion and a laterally-flaring rear portion, and alsohaving a grain channel passing vertically therethrough, which channel atits lower end is divided to form diverging branches, the lower ends ofwhich pass through the bottom of the runner at a considerable distanceon each side of the center of the shoe.

In testimony whereof I sign this specification in the presence of twowitnesses.
